Thermal Resistance of Blown Bitumens to The Conditions of Sharp-continental Climate

Bagdat Teltayev and Evgeniya Kaganovich

Abstract:
The studies the results of which are presented in the article have been performed to evaluate blown bitumen resistance in the temperature range characteristic of Kazakhstan’s sharp-continental climate. The tests were performed at different temperatures using the Superpave methods and devices. The comparison of the values of shear complex modulus, stiffness and relaxation rate index with the specified values has indicated that the bitumens applied meet the climatic conditions requirements only for the part of the territory and the use of polymers is required to improve the thermal resistance. The thermal resistance shall be determined at the asphalt concrete mix design.
